DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a dispenser for a medium which is at least partially solid or which can be flowable, such as liquid, pasty and / or gaseous. About. Preferably, the medium is a particulate or powder and is therefore suitable as a bulky medium. The dispenser is gripped with one hand and simultaneously operated with that hand. As a result, pharmaceuticals, cosmetics or similar media are released. The dispenser can be designed for application to the respiratory system, ie, for nasal or oral administration.

[0002]

BACKGROUND OF THE INVENTION The dispenser can be provided for a single dispensing operation, i.e., for stroke movement in a single and single direction only. Therefore, the return means for returning it from the end position to the initial position, that is, the rest position, can be omitted. It is also possible for the dispenser to allow several successive actuation strokes, each restarting from a different position, ie a designated rest position.

To dispense precisely dispensed media volumes of up to 30 mg, 20 mg, 15 mg or 12 mg and a minimum of 5 mg, a very compact dispenser will suffice. The reservoir chamber containing the medium pre-dispensed for a single dispensed dose is an oval capsule, cup, flat tray or spherical dome.

The depth of the reservoir chamber cup is:
It can be 7 mm, 5 mm or 4 mm or less and 2 mm or more. Its maximum diameter is 20mm, 15mm
And 10 mm or less, 3 mm or 6 mm or more, or greater than the cup depth. The reservoir or magazine body can be dimensionally stable or flexibly bendable in the zone connecting to the rigid chamber. It is formed by a thin film wall like a transparent or opaque blister. Prior to dispensing, the filled reservoir chamber is closed in a gas-tight and sterile condition. Therefore,
The closure is formed by a thin film of plastic or a metal foil, such as aluminum, which is mounted in an adhesive or hot sealing manner. German Patent Application 197 04 8

[0010]

In accordance with the present invention, means are provided for effectively producing functional movement of the reservoir during the course of a dispense cycle or associated operation. Such movements are linear stroke movements,
It is also possible for the positioning movement to be transversely directed to it, or for the opening movement to be directed transversely to said positioning. Due to the alignment movement, the reservoir is moved from a protective rest position of the reservoir chamber to a position determined for dispensing. Due to the opening movement, the wall, in particular the chamber lid providing the outlet closure, is provided with an outlet opening for the medium. Due to the stroke movement, the finished dispenser can be shortened so that it is held particularly effectively in the hand during dispense. The opening movement begins just before or together with the alignment movement, and the alignment movement ends before or after the opening member engages the closure of the reservoir chamber,
It does not end before the opening movement ends. The stroke movement is used to control or open additional outlet closures or valves, to convey a second medium, to stop and limit the maneuvering movement or stroke, to prime the second medium, etc. You will get.

[0011] The reservoir support accommodating said reservoir in a replaceable manner, in particular over its functional stroke and not over its operating stroke, but also over its alignment movement as required, It can move synchronously with the reservoir. The reservoir support includes:
It is possible to form a compartment or cylinder or plunger of a compression chamber or pump chamber, which can comprise opening means for said outlet closure, to form its stop; To the reservoir chamber, it is possible to throttle the outlet duct for the second medium to be throttled prior to the start of this medium flow, forming means for counting the discharge cycles or It is possible to form an indicator for the counting means, to improve or reinforce the mutual attachment of the two bases or casing units, and to define an annular chamber adjacent to the outermost dispenser wall. To form an abutment for the return spring or a downward holder for said reservoir. And capable of movably or rotatably receiving the reservoir except for being centered, resiliently tensioning one of the base units and across the stroke And so on.

The lid includes a stud having a media outlet, an opening member, a mounting member of the positioning device, a means for positioning the reservoir without play, an operating handle, and an abutment for a spring or the like. Is included. The lid may be axially mountable, radially insertable or pivotable, and may be disposed on an associated housing portion, and may extend to the reservoir chamber. It is also possible to define a portion of the outlet duct for the two media or the outlet duct portion from the reservoir chamber to the media outlet. All of these functions can also be performed by single or multi-part components. The remaining housing part associated therewith centers the reservoir or the reservoir support and provides escape protection which prevents the associated unit from being withdrawn axially from the other unit. Form. In addition, this housing part can directly drive the reservoir or the reservoir support over the relevant stroke path with respect to the other housing part. In its closed position, the lid and the associated housing part will be positioned and secured to each other via a snap connector, resulting in a seal.

[0013] The positioning movement can also be performed by mutually servicing circumferential serrations having inclined flank like counter-means means. U.S. Pat. No. 4,565,302, filed Jan. 13, 1984, is referred to as further features and advantages described therein as being encompassed by the present invention.

[0014] Specific embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

[0015]

DETAILED DESCRIPTION FIG. 1 shows a dispenser 1 comprising two basic units 2, 3 which are manually movable axially with respect to each other. The units 2, 3 form a housing which receives the further unit 4 throughout its interior. The length of the unit 4 corresponds to at least one third or one half of the spacing between the large outer end faces or handles of the units 2,3. Further units 5
That is, the reservoir is disposed in the bases 2 and 3 as a whole. The units 4, 5 are not only movable with respect to each other and independently of each other, but also with respect to each of the units 2, 3 together, ie both axial movement and transverse or rotational movement. Can also exercise together. The units 2 and 3 are permanently prevented from rotating with each other. A further sub-unit 6 of unit 3 is movable with unit 3 for each of units 2 to 5.

The media outlet 7 opening to the environment is movable with respect to the units 2, 4, 5 together with the units 3, 6, respectively. The means 8 comprises a housing 2, 3 as a whole.
And a second medium, such as air, is delivered. The second medium is supplied first to the medium and subsequently to the outlet 7 via an outlet closure 9, ie a resiliently closed valve. The shaft 11 of the outlet 7 is
The units 2 to 5 are eccentric with respect to the center or main axis 10. The first medium flows inside the units 2, 4 and 5 and in the direction 12 away from the unit 2 the axes 10,
It will flow parallel to 11 upstream of the outlet 7 and will exit the dispenser 1 in direction 12.
To operate from the rest position shown in FIG. 2, the units 3 to 6 are manually moved in the axial direction 13 with respect to the unit 2.

The reservoir 5 has an integral deep-drawn or injection-molded base body that contains a number of eight chamber bodies 15 evenly distributed about the axis 10. . The reservoir 5 also has a separate flat outlet or foil closure 16. Each chamber body 15 has a spherical cap or reservoir chamber 1.
4 is formed. Chamber 14 has a maximum chamber depth that is less than the radius of the sphere. Thus, the chamber compartment gradually expands until it reaches the flat chamber opening 17. The spherical cap or body 15 projects beyond only one side of a flange or reservoir plate 18 integrally formed with the cap 15. The sides of the opening are also covered by an annular disc-shaped closure 16. The inner circumference of the plate 18 has at least one driver 19, for example a projection, a tooth or the like. The driver 19 engages with the unit 4 in an axially movable and retractable manner, but securely engages in the rotational direction. Driver 19
Transports the reservoir 5 together when the unit 4 is rotated about the axis 10.

The means 20 for breaking and opening the closures 16 are provided in the shaft 11 and are provided only in the vicinity of each single opening 17.
To release. The means 20 belong to a discharge stud 21 which projects freely and is traversed by the outlet 7 at its free end face. Straight nozzle 21
Has an outermost conical shell 22. The inner shell 23 is radially spaced from the shell 22 and disposed therein. The shell 23 is traversed by an outlet duct 24 having a width of at least 2 mm up to 5 mm and having a constant cross-sectional area until reaching the outlet 7. The shells 22, 23 transition so as to be integral with each other at the outermost end of the stud 21. The inner end of the shell 23 has an integral opening member 25, such as a piercing or tearing member. Upon axial or rotational movement about the axis 10, the member 16 can be rapidly opened at said point where the chamber 14 is in each case aligned with the axis 11. The radial spacing of the center of each chamber 14 from the axis 10 of the reservoir 5 is equal to the spacing between the axes 10,11. U.S. Pat. No. 5,469,9
According to No. 89 (filing date June 25, 1991), the reservoir 5 can also be operated with a plunger for said medium. This document is referred to as having its features and advantages included in the present invention.

The unit 6 is mounted on the unit 3 by hinges 27 for pivoting by exactly 90 degrees or more. The axis of the hinge is
The axes 10, 11 are oriented at right angles to the common axial plane. The shell 22 is integrally connected to a flat end wall 26 by its widened end, said end wall forming the end wall of the unit 3 remote from the unit 2. The wall 26 forms a handle 28 on the outside thereof, which is provided with a protrusion for higher gripping ability. The handle 28 functions to actuate the unit 3 in a compressive manner. On the side of the shaft 10 remote from the shaft 11, the wall 26 forms a bearing body for the associated bearing 27. The axis of the mounting 27 can be close to the plane of the handle 28. Inside that wall 26
Has a radially elastic snap member 29 projecting annularly along its outer circumference. The member 29 is a unit 6
Is in its operating position, the unit 6 is positioned and fixed on the unit 3 without play.

The installation means 30 is provided between the end wall 26 and the unit 4 inside the unit 3. In each actuation stroke, the means 30 switches the reservoir 5 forward around the axis 10 with or without the unit 4. Thus, the next chamber 14 that is still to be opened is aligned with the shaft 11. The sleeve or positioning member 31 projects integrally from the inside of the wall 26. The member 31 is directly juxtaposed with the shell 22, and has a rotating member uniformly distributed around its inner circumference, i.e., an axial web with laterally inclined ends. A complementary positioning member 32 on the outer circumference of the sleeve projects in the opposite direction from the unit 4 and can be integral with the unit 4 or formed by a separate socket. The mutual actuation stroke of the units 3, 4 will cause one of the above-mentioned alignment steps of the reservoir 5. This is because the members 31, 32 only engage one another thereafter. The members 31 and 32 are
Are closely surrounded by a permanently pre-loaded compression spring 33 adapted to be annularly supported by one end of an abutment 34 inside the. The other spring end is annularly supported on the reservoir 5 or portions 16,18. Therefore, the reservoir 5 is pressed against the unit 4. At the end of the stop-limited stroke of the means 30, the member 32 will be slightly spaced from the wall 26.

The unit 3 forms a housing part 35 adapted to include an annular end wall 36 which connects to the wall 26. The outermost shell 37 and the inner shell 38 are
It freely projects from the wall 36 in the direction 13. Shell 3
8 is located inside the shell 37 and is radially spaced therefrom. Thus, from the inside of the wall 36, a narrow annular groove emanates, as defined by the shells 37, 38, to be engaged with the unit 2. The wall 36
It has a recess for receiving the generally counter-sunk plate 26. Plate 26 also surrounds shell 22. Thus, the outsides of the walls 26, 27 are interconnected flush, i.e. without gaps, on the same plane. Opposing member 3
9 project above the wall 36 along the inner circumference of this recess.
The interengaging snap sheets of members 26, 36 and 29, 39 are airtight and may also create a labyrinth seal.

The downward holder 40 positions and fixes the reservoir 5 on the unit 4 in the axial direction. The associated end of the spring 33 is supported directly on the body 40 and is centered. Instead of the design shown in solid lines,
The locking body 40 can additionally have a configuration 41 indicated by a dashed line. The bodies 40, 41 are then provided with the sleeve part 40 in the shaft 10 and the shaft 11.
And a sleeve portion 41 in the inside. Unit 4
With respect to the air flowing through the closure 9 between the and the wall 26, the interengaging members 26, 31, 32, 40 form a double duct. That is, they have a transverse deflection 42, a first deflection that is transverse to the axis 10, and a subsequent direction 1 between the circumference of the members 31, 32.
3 to form the deflection. The flow velocity is greatly increased by a correspondingly reduced flow cross section in this return deflection. Downstream of the return deflection, all air is aimed at the bottom of the chamber 14 when in the axis 11. That is, it is the axis 10
Is directed radially outward from the chamber portion that is close to.

As a result, in the chamber 14,
The flow will cause a swirling or rotating flow around the axis 10 or shell 23. Said flow is a spiral flow flowing directly into the duct 24 and the chamber 1
Get out of four. Therefore, the support 40
It has an annular pressurized and sealed end surface 44 adapted to extend about axis 10. During rotation, surfaces 44 of portions 40 and 41 are pre-tensioned and rested or slidably closed on closure 16 or plate 18. Surface 44 is traversed by a groove or transverse duct 43 directed towards axis 11. The air flows through the duct 43 after a return deflection which is guided obliquely with respect to the bottom of the aligned chamber 14. The outer end of the holder 40 engages with the outer periphery of the main body 31 via the snap and sealing connector 45 by its inner periphery. On the member 31, the holder 40 is axially displaceable and, in addition, is rotatable or prevented from rotating. At the stroke end of the mounting means 30, the support 40 can abut the inside of the wall 26 or on the mount 34, resulting in a manifold with increased support or pushing force. The supports 40, 41 can also be integral with the spring 31, the wall 26 or the member 31, for example a bellows.

The portion 41 is expediently elliptical when viewed from the axial direction, and is spaced from the shafts 10 and 11 by the holder 4.
0 is integrally connected. At its end remote from reservoir 5, section 41 has an end wall permanently traversed by tube 23. This end wall has a lip that slides hermetically on the outer circumference of the tube 23. Accordingly, the sealing pressure is increased by the fluid pressure inside the part 41. The surface 44 of the support 40 covers the opening 17 and engages towards the central axis of said opening. The part 41 is oriented with respect to the chamber 14 to be evacuated, while being exclusively aimed at it,
It also allows air to pass through a narrow flow cross section. Thus, the remaining chambers 14 or their closures 16 cannot be blown.

The sleeve member 32 is spaced from the base body of the unit 4 and is rotatable about the axis 10 therewith. Member 32 connects to the base body via a rotor or freewheel coupler 46 which permits rotation of coupler member 32 relative to the base body in the same direction as the alignment movement. However, on the other hand, this rotation in the opposite direction is reliably prevented. The coupler member radially inward of the base body can be star-shaped with resiliently bendable locking arms projecting at an angle as shown in FIG. is there. At its outer periphery, the coupler member 32 has a rotary driver 47 that is complementary to the driver 19. The driver 47 is
It has two cams projecting radially and distributed evenly in the circumferential direction. Between the side flanks of these cams and around the shaft 10, the cams, which are uniformly dimensioned in the circumferential direction of the driver 19, can be used without radial play.
Engage with.

The integral base body of unit 4 has an annular end wall 48 and a cylinder jacket 51 projecting from wall 48 in direction 13. Walls 48 and 51 are
It is arranged in the radial direction inside the shell 38, or is connected to the inner periphery of the shell 38 in a manner that it can be displaced in the axial direction but is sealed. The wall 48 has a recess 49 on its outside for receiving the body 15. The recesses 49 are formed by individual recesses distributed in the circumferential direction to center the reservoir 5. Dent 4
9 can alternatively be a continuous annular groove around the axis 10 for rotating the reservoir 5. Each body 15 is continuously supported on the depression 49 over at least a large spherical circle reaching the plate 18. The plate 18 is fully supported around each individual recess or on both sides of the groove 49 until it reaches the driver element 19 on the outer end face of the wall 48. Member 32 is also axially supported on this outer end surface.

The inside of the wall 48 forms an abutment 52 for a return or compression spring 59 that is considerably stronger than the spring 33 and allows for a greater pretension to be permanently applied. . A spring 59 is radially centered and engages the bearing 52. The tubular casing 53 of the closure 9 projects radially beyond the inside of the wall 48 inside the bearing 52 and also in the direction 13. The hollow projection 54 protrudes beyond the outside of the wall 48 and is also an insertion portion of the coupler 46. The star shaped outer periphery of the insert 54 is provided with a resilient clasp member of the coupler adapted to engage the inner periphery of the member 32. The member 32 may be integral with the base body 4 or may be axially inserted without play by a snap connector over the bayonet 54 and positioned and locked. This connector can at the same time be a rotary bearing for rotating the member 32 with respect to the body 4.

Element 55 which is a movable closure and valve
Is arranged inside the free end of the casing 53. Ball 55 is biased against its valve seat in housing 53 by spring 56. The housing space of the shells 53, 54 receives the parts 55, 56 and forms a duct, said duct being arranged in the shaft 10 like the shells 53, 54. This duct connects the means 8 to the duct 42. Shell 51 is surrounded by outer shell 58 at a predetermined distance from wall 48. The shells 51, 58 are spaced apart in the radial direction.
Shell 58 is also permanently supported on unit 2. The spring 59 is arranged inside the shells 51 and 58.

The opposite ends of the shells 38, 58 provide a driver or drag means 60. The free end of the shell 38 is a driver 61 and the shoulder at the opposite end of the shell 58 is the abutment associated therewith. The inner circumference of the shell 38 is slidably guided on the outer circumference of the body 4. In the rest position, the surfaces 61, 62
Are separated from each other by the force of the spring 33. This interval corresponds to the operating stroke of the means 20, 30.

Like unit 3, unit 2 also
The end wall 63 and the two telescoping shells 64, 65 form a cup or housing, which protrudes only in the direction 12 from the wall 63. The free end of the inner shell 65 forms a piston 66 or piston lip, which slides on the inner circumference of the shell 51 until it reaches the wall 48.
The valve casing 67 projects from the bottom 63 into the shaft 10 only in the direction 12 with the relevant part of the inlet valve.
Thus, means 8 forms a compressed air pump 50, a thrust piston pump. In the return stroke, the pump 50 will again draw in air from outside via the ball valve or pressure relief valve 67. The outside of the wall 63 forms another handle 69. The control or opening means 70, after a given pump stroke, regardless of the stroke path of the means 20, 30, 60
Included to release The valve 9 can also be opened at a predetermined overpressure in the pump chamber. The means 70 comprises a mandrel 71 in the axis of the member 55, said mandrill projecting freely in the direction 12 from the parts 63, 67. Towards the end of the pump stroke, the mandrel 71 will penetrate and abut into the inlet opening of the housing 53, and will then drag the ball 55 over a small opening stroke. The opening member 71 in this case is snap-fitted over the free end of the casing 67 together with the cap, and closes this end.

The units 2 and 3 include a lock and a snap
The connector 73 reliably prevents mutual pull-out. The units 2 and 3 are connected to the shaft 10
Are prevented from rotating around each other. Furthermore, the units 2 and 3 are prevented from being pulled out of each other by the snap lock 75. Thus, shell 64 has a thickened edge bead 76 at its free end, said bead comprising shell 6
4 continuously extends around the inner circumference. At its outer periphery, the bead 76 forms a snap and anti-rotation member projecting away from each other of the locks 73,74. For these members, the inner periphery of the shell 37 has a groove or locking recess 74. Therefore, at the free end of the shell 37 and between the side flanks of each groove, a snap member 77 protruding radially inward of the lock 73 is formed. For the lock 75, the shell 58 has a snap member 78 at its free end, said snap member protruding beyond its outer circumference. Member 7
8 slides continuously and hermetically on the inner periphery of the shell 64 in the circumferential direction. Thus, member 76 forms an opposing member for the three locks 73-75.

A narrow annular groove is formed between the perimeters of the shells 51, 58. Both shells can be permanently supported by radial pretension on their opposing surfaces 66,64. The same is true for shells 37, 64. In the pump stroke, the shells 51, 58
Are plunged into an annular chamber 68 between the shells 64,65. At its bottom, the chamber 68
Is defined by a transverse rib forming a stop for said pump stroke.

The parts 63 to 67 and 69 of the unit 2
Is one thing. The same is true for parts 36 to 39, 77 of unit 3 and parts 4 of unit 4
The same applies to 8, 49, 51 to 54, 57, 58, 78. For unit 3, parts 22-2
In addition to 6, 28, 29, the parts 33, 40 can also belong to an integral body.

In operation, first, means 29, 30, 6
An opening stroke of 0, a pump stroke and an idle stroke are performed together. Before the rotational movement of the means 30 is completed, the spikes 25 have already penetrated the closure 16 in the axial direction. Thus, further rotation down to the axis 11 will further open up the transverse movement between the spike 25 and the closure 16. At the end of this stroke, the spike 25 did not reach all the way to the bottom of the chamber 14, but its inlet opening is completely located in the chamber 14. Subsequently, the means 60 will drag the unit 4 with respect to the unit 2 in synchronization with the unit 3. Thus, air is pre-tensioned in the pump chamber with valve 9 closed. Following the largest portion 82 of the pump stroke 81, the bayonet 71 will synchronously drag the ball 55 to its open position. Therefore, the compressed air passes through the duct 56 and reaches the outlet 7, as described above,
Run away without a valve. As a result, the member 76
It will pass over surfaces 61 and 62. At the end of the stroke, the member 76 is located in an annular groove defined by the portions 36-38. Handle 28, 6
When 9 is released, means 9, 20, 30, 40, 50,
60, 70 are simultaneously exposed to the forces of springs 33, 56, 59 and return to their rest position. As a result, the unit 4 does not need to be limited directly to the stopper in the axial direction with respect to the unit 3. In the return movement,
The valve 67 opens so that air is drawn in. The reservoir 5 will not need to perform a rotary movement during the return movement.

After all media portions of the reservoir 5 have been expelled, the unit 6 can be opened at an angle, as shown in FIG. As a result, the parts 21,2
5,29,31,36,40 also followed
The parts 5, 32, 48, 49 can be freely accessed from above. Thus, according to FIG. 1, the reservoir 5 can be removed upwards or can be inserted in the direction 13. All components cited can be injection molded from plastic material. All properties and effects can be provided exactly as described,
Alternatively, it may simply be provided substantially or roughly, and depending on the particular requirements, it may also be possible to deviate significantly therefrom. Handle 28, 6
The spacing between 9 can be equal to the largest outer diameter of the dispenser 1. Conveniently, each of these dimensions amounts to a maximum of 70 mm or 60 mm, with the dimensional relationships as shown being particularly preferred. The units 3 to 6 are particularly easy to assemble.
